Ancient Beast has adventure and combat mode and they’re both based on square tiles / grid. So the targeting/path-finding/AI/map editing/generation will be based on it. Perhaps you would be interested in helping out as well?
(perhaps you’re familiar with homm3 or homm5, disciples 2, age or wonders 2 or something similar in order to get a better overall idea)Anyway, you can find more info in the projects page, documentation still lacks a bit of love but if you have questions, don’t hesitate.
The project is bigger, people are involved and things are on the right path, so don’t expect this to be abandoned and such.
